OBJECTIVE Which physical findings and blood parameters predict postpartum hypertension remain to be studied in women with twin pregnancies. METHODS The antenatal systolic and diastolic blood pressures (SBP and DBP, respectively), and 16 laboratory variables were investigated in 150 normotensive women who gave birth to twins. RESULTS When the median values of the 18 continuous variables were used as cut-off values, an SBP>120 mm Hg (relative risk [95% confidence interval], 2.81 [1.94-4.08]), a DBP>70 mm Hg (2.42 [1.68-3.49]), an aspartate aminotransferase level>18 U/L (2.22 [1.55-3.19]), and a uric acid level>5.3 mg/dL (1.68 [1.20-2.36]) were independent risk factors for postpartum hypertension. CONCLUSIONS Antenatal blood pressure measurements and a laboratory work-up may be useful clinically for predicting postpartum hypertension in women with twin pregnancies.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures

D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D011644 Puerperal Disorders Disorders or diseases associated with PUERPERIUM, the six-to-eight-week period immediately after PARTURITION in humans. Disorder, Puerperal,Disorders, Puerperal,Puerperal Disorder
D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.
